Dose and duration of SERM treatment will vary based on length of cycle and compound(s) used.
For short duration cycles with mild compounds, a 3 week treatment with a SERM should suffice, for 4-8 weeks of moderate compounds, a 4 week treatment should suffice. For over 8 weeks, we start seeing 6 weeks as being better. Remember, it isn't only the dose, its the time it takes for you to get your own production up as well.
One other compound worth mentioning that isn't (usually) included is HCG. For any cycle longer than 8 weeks, it is a good idea to use HCG to keep the testicles primed and ready for SERM therapy. A dose of 250iu 2x a week is a good amount for this. Just make sure to stop the HCG ~3 days before you start the SERM, as it is a bit suppressive on its own.
The exeptions to this are in these programs:
HPGA Normalization Protocol After Androgen Treatment
N Vergel, AL Hodge, MC Scally
Program for Wellness Restoration, PoWeR PoWeR : Program for Wellness Restoration
Day 1-16 : 2500iu HCG every other day.
Day 1-30 : Nolva 20mg/day; Clomid 100mg/day (50mg was taken twice per day)
Day 31-45 : Nolva 20mg/day

Vit E: 1,000iu/1,000iu/1,000iu/0/0/0
Both of these are meant to re-start after HEAVY and LONG cycles, not your average 12-16 weeker.
The second required compound in a PCT is a mild AI (Aromatase Inhibitor)(explained by matt's wisdom above). You want a mild AI for this application, preferably with a short half-life and easily adjusted dosages. This will usually be used in a taper down as well, but started a couple weeks into SERM therapy and ran past it due to the fact that estrogen is more likely to be an issue as the SERM dose is lowered.
There are other things worth including in a PCT to make it easier to hold gains. Some of the basics are:
Cortisol Control (Cortisol eats muscle like a keto-dieter eats meat, and uses the same “raw” material as testosterone (cholesterol), so lowering its production is a double-win. For example Suppress-C/Erase/Erase Pro).
Natural Test Booster(s) (to get your boys going even faster, DAA is very solid here).
Natural Anabolics (to help hold the gains, like Anabeta).
Glucose Disposal Agents (to help prevent fat storage: Need2Slin, Recompadrol, Slin Sane).
A couple other compounds worth mentioning for PCT are: Forma Stanzol which has anti-e properties as well as raising IGF-1 levels, and increasing HPGA activity (it can also be used on cycle for these benefits (minus HPGA activity), as well as increasing the effectiveness of other androgens in your system. The other compound is Ostarine, which is a SARM (Selective Androgen Receptor Modulator), which functions like a natural anabolic and a nutrient partitioner.
One final mention goes out to Primordial Performance for their Testosterone Recovery Stack (TRS). The TRS is a compliment of products that handles cotrisol control, helps boost testosterone production, and helps force the conversion of cholesterol into testosterone.
Finally we get to training and eating during PCT. This is where a lot of people mess up. They've just finished up a bulker and want to immediately get rid of the extra bits of fat they've accumulated, so they drastically cut calories and start doing stupid-crazy amounts of cardio, and then wonder where their gains have gone by the time they finish PCT.
If you haven't been able to surmise by now, PCT is not the time to push your body to do *anything* besides recover. Calories should be no lower than maintenance, cardio should be very mild (and for health only, not fat destruction), and weight training should be mild. When it comes to these aspects, it really is that simple.
I hope this thread makes PCT easier to understand and plan for all of you.
